Carpenter bees can be timber pests, and cause substantial damage to wood if infestations go undetected for several years. [12] Two very different mating systems appear to be common in carpenter bees, and often this can be determined simply by examining specimens of the males of any given species. Species in which the males have large eyes are ...
Xylocopa sonorina, the valley carpenter bee or Hawaiian carpenter bee, [2] is a species of carpenter bee found from western Texas to northern California, [3] and the eastern Pacific islands. [4] Females are black while males are golden-brown with green eyes.
Female X. virginica. The bee is similar in size to bumblebees, but has a glossy, mostly black body with a slight metallic purple tint. [4] X. virginica males and females have generally the same mass, but can be differentiated visually by the male's longer body and the female's wider head. The males also have a white spot on their face.
The hollow can reach 30 cm (12 in) long by 1.1-1.4 cm diameter. Larger pieces of wood may allow for multiple tunnels. Several female bees may use a nest, one breeding and the others guarding. A bee defends the 0.7-1.0 cm wide entrance by blocking it with its abdomen (compare Allodapula). Both male and female bees may overwinter within the tunnels.
The Oriental carpenter bee, Xylocopa nasalis, or Xylocopa (Biluna) nasalis, is a species of carpenter bee. It is widely distributed in Southeast Asian countries. It is a major pollinator within its ecosystem, and is often mistaken for a bumblebee. [2] The species leads a solitary lifestyle with a highly female-biased colony in the nest. [3]
As with other carpenter bees, the larvae are fed a mixture of pollen and nectar. The females have a mutualistic association with phoretic mites that are transported from nest to nest in an abdominal chamber, called the acarinarium. [2] [3] The mites feed on nest fungi that may otherwise infest the nectar and pollen provisions of the larvae. [2]
Xylocopa pubescens is a species of large carpenter bee. Females form nests by excavation with their mandibles, often in dead or soft wood. X. pubescens is commonly found in areas extending from India to Northeast and West Africa. It must reside in these warm climates because it requires a minimum ambient temperature of 18 °C (64 °F) in order ...
Adult size is directly correlated to the quantity of food the individual received as a larva; in order to produce successful female offspring, the mother bee must do more work foraging compared to the work needed to produce male offspring. [9] This is due to the female bee's greater size than their male counterpart. Daughters are roughly 8% ...
